Simulation of the Mechanical Behavior of Nanodispersed Elastomer Particle-Modified Polyamide 6

Abstract

In this work the nanodispersed elastomer copolymer particle-modified polyamide 6 (PA 6) is investigated. Micromechanical modelling is proposed to predict the mechanical behaviour of this material up to failure. A three-dimensional self-consistent embedded unit cell model is chosen which has been well applied for simulating the elastoplasticdeformation of this PA 6-composite [1,. This model will be here modified with the consideration of debonding between the elastomer particles and the PA 6-matrix. The predictions are in very good agreement with the experimental results. In terms of crash behavior, e.g. in the automotive industry the material behaviour under dynamic loading is also of particular interest. Impact strength is one of the most important parameters for describing this material behaviour. A full three-dimensional dynamic simulation of V-notched Charpy impact test is performed in ABAQUS/Explicit. The calculated impact strength coincides plausibly well with the experimental determination.
